It’s long been recognized that an effective way of staring a fight in a bar catering to pilots is to innocently ask about procedures for hot starting big-bore Lycoming or Continental engines and then step back. The chairs will start flying.
That’s about what happened when we started the research for this piece. We heard it all. Being either foolish or fearless, we immersed ourselves in the subject to see if we could come up with information as to why hot starting is a problem, find recommendations for maintenance and operating technique that can minimize the problem and see if there are aftermarket devices that can help. We did, we did and there are.
